Method for realizing active transaction flow limiting through API interface in financial transaction

Abstract

The invention, which belongs to the technical field of the financial transaction background, discloses a method for realizing active transaction flow limiting through an API interface in a financial transaction. The distributed system employed by the method is an independent service management system separated from a service provider and a service invoking side. A financial transaction API interface is registered into the distributed system and service classification is carried out on the API interface in the distributed system; according to a TPS indicator of a service provider system, the invoked frequency of the API is monitored; when a certain order is reached, closing is carried out automatically in an ascending order according to the advanced divided priority of the transaction; andafter closing, if the invoked frequency of the interface is recovered to a certain degree that can be set in advance, starting is carried out automatically in a descending order based on the priorityof the closed transaction. Therefore, transaction monitoring and automatic and elastic flow limiting are realized.

Description

technical field [0001] The invention relates to the technical field of financial transaction background, in particular to a method for realizing active current limit of transaction through API interface in financial transaction. Background technique [0002] In the field of financial transactions, the existing transaction model is a service provider and a service caller. The service provider provides an external service call API interface, and the service caller implements the service by calling the above API interface. At the beginning of the design of the system, there will be an estimated capacity. If the TPS / QPS threshold that the system can withstand is exceeded for a long time, the system may be overwhelmed, and eventually the entire service will be insufficient. In order to avoid this situation, it is necessary to limit the request of the API interface. The purpose of current throttling is to protect the system by limiting the rate of concurrent access requests or th...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that all current methods for limiting the flow of API interfaces are passive flow-limiting methods, which are less flexible and cannot actively discover and perform current-limiting in advance by predicting the transaction situation, resulting in when the transaction volume When there are too many, the system pressure is too large and the entire business application system will be dragged down, and the service provider and the service caller will suffer heavy losses. The present invention provides a method for actively limiting the transaction flow through the API interface in financial transactions
